Create JOG Elevation Tint Bands from Features

Краткая информация

Converts contour polylines into elevation tint band polygon features. The features can be used to represent different elevation levels on a Joint Operations Graphic (JOG).

Использование

• Use contour lines that have been collected using meters.

• The feature layers specified for the Contour Feature Class and Exclusion Feature Classes parameters must all contain the field listed in the Contour Elevation Field parameter.

• The Elevation Units parameter value applies to all the feature layers specified for the Contour Feature Class and Exclusion Feature Classes parameters.

• This tool may generate holes around the corners of AOI Feature Class features. Set a high AOI Buffer value to correct this. Do not use a negative value for this parameter.

Синтаксис

CreateJOGElevationTintBands(AOI_Feature_Class, AOI_Field, AOI_Buffer, Contour_Feature_Class, Contour_Elevation_Field, Contour_Elevation_Units, Output_Feature_Class, Output_Feature_Class_Units, {Exclusion_Feature_Classes})

Параметр	Объяснение	Тип данных
AOI_Feature_Class	The area of interest for the JOG. This feature is typically stored in an index feature class.	Feature Layer
AOI_Field	Поле, содержащее уникальный идентификатор для каждой области интереса.	Field
AOI_Buffer	Буфер для применения к объектам входной области интереса. Буфер расширяет геометрию AOI Feature Class, чтобы включить объекты в Contour Feature Class, который располагается за пределами AOI. Это может улучшить точность вычисления полосы, которая используется для генерации полигонов.	Linear unit
Contour_Feature_Class	The feature layer that contains the contours. The information for the output bands will be derived from these features. This must be a polyline feature class.	Feature Layer
Contour_Elevation_Field	The field in the contour feature layer from which the elevation values will be derived.	Field
Contour_Elevation_Units	The unit of measurement that has been used to collect the contours and exclusion features. METERS —The contours and exclusion features have been collected using meters. This is the default. FEET —The contours and exclusion features have been collected using feet.	String
Output_Feature_Class	The feature class that will contain the banding features.	Feature Class
Output_Feature_Class_Units	Output band distance units. METERS —Units in meters. FEET —Units in feet.	String
Exclusion_Feature_Classes [Exclusion_Feature_Classes,...] (Дополнительный)	Feature layers that define areas for processing exclusion. Excluded areas will not be taken into account when calculating the percent area ratio for the output bands.	Feature Layer

The following stand-alone script demonstrates how to use the CreateJOGElevationTintBands tool.

# Name: CreateJOGElevationTintBands_Example.py
